Description

Technical Field

[0001] This utility model belongs to the field of microphone technology, and more specifically, it relates to a KTV voice-controlled ambient color wireless microphone. Background Technology

[0002] Traditional KTV wireless microphones mainly focus on audio transmission quality and wireless connection stability, but have significant shortcomings in user experience and atmosphere creation. There are two main types of products in the existing technology: one is a microphone without light configuration, which has a single function and is difficult to create an immersive atmosphere in entertainment scenarios such as KTV; the other is equipped with always-on LED light groups, but generally has the defects of fixed lighting mode and inability to link with sound field. Specifically, it is manifested in the following ways: (1) The lighting control circuit and the sound pickup module are independent of each other and cannot convert sound pressure changes into light effect parameters in real time, resulting in the lack of sound and light interaction effect; (2) The light groups mostly adopt a ring or straight line arrangement, which limits the light diffusion angle and cannot form a three-dimensional surround visual effect; (3) Insufficient heat dissipation design makes high-power LED beads easy to overheat, affecting the light effect stability and device life; (4) The always-on working mode causes energy waste, which is contrary to the current green energy-saving design concept.
